Detailed Description

template<class T>
class OpenSim::Set< T >

A class for holding a set of pointers to objects.

It is derived from class Object and is implemented as a wrapper around template ArrayPtrs<T>. It is implemented around an array of pointers, rather than values, so that it can make use of any virtual methods associated with class T.

	)

inline

Add an object to a group.

template<class T>

virtual bool OpenSim::Set< T >::adoptAndAppend ( T * aObject )

inlinevirtual

Append to the array, and adopt passed in pointer.

A copy is NOT made of the specified object. If getMemoryOwner() is true, this Set takes over ownership of the object and deletes it when the Set itself is deleted.

Parameters

aObject Object to be appended.

Returns: True if the append was successful, false otherwise.

template<class T>

virtual void OpenSim::Set< T >::clearAndDestroy ( )

inlinevirtual

template<class T>

virtual bool OpenSim::Set< T >::cloneAndAppend ( const T & aObject )

inlinevirtual

cloneAndAppend creates a clone of the passed in object and appends the clone to the array.

The original object is unaffected and is not associated with the Set. The clone is created using the method clone() available to OpenSim::Object

Parameters

aObject Object whose clone is to be appended.

Returns: True if the append was successful, false otherwise.

template<class T>

bool OpenSim::Set< T >::computeNewCapacity	(	int	aMinCapacity,
		int &	rNewCapacity
	)

inline

Compute a new capacity that is at least as large as a specified minimum capacity; this method does not change the capacity, it simply computes a new recommended capacity.

If the capacity increment is negative, the current capacity is doubled until the computed capacity is greater than or equal to the specified minimum capacity. If the capacity increment is positive, the current capacity increments by this amount until the computed capacity is greater than or equal to the specified minimum capacity. If the capacity increment is zero, the computed capacity is set to the current capacity and false is returned.

Parameters

rNewCapacity	New computed capacity.
aMinCapacity	Minimum new computed capacity. The computed capacity is incremented until it is at least as large as aMinCapacity, assuming the capacity increment is not zero.

Returns: True if the new capacity was increased, false otherwise (i.e., if the capacity increment is set to 0).

template<class T>

virtual void OpenSim::Set< T >::getNames ( OpenSim::Array< std::string > & rNames ) const

inlinevirtual

Get names of objects in the set.

Parameters

rNames Array of names. The names are appended to rNames, so it is permissible to send in an non-empty array; the names in the set will simply be appended to the array sent in.

template<class T>

int OpenSim::Set< T >::getNumGroups ( ) const

inline

Get the number of groups.

template<class T>

int OpenSim::Set< T >::getSize ( ) const

inline

virtual bool OpenSim::Set< T >::insert	(	int	aIndex,
		T *	aObject
	)

inlinevirtual

Insert an object into the array at a specified index.

A copy of the specified object is NOT made. If getMemoryOwner() is true, this Set takes over ownership of the object and deletes it when the Set itself is deleted.

This method is relatively computationally costly since many of the array elements may need to be shifted.

Parameters

aObject	Object to be inserted.
aIndex	Index at which to insert the new object. All current elements from aIndex to the end of the array are shifted one place in the direction of the end of the array. The specified index must be less than or equal to the size of the array. Note that if aIndex is equal to the size of the array, the insertion is equivalent to an append.

Returns: True if the insertion was successful, false otherwise.

Reimplemented in OpenSim::ModelComponentSet< T >, OpenSim::ModelComponentSet< ExternalForce >, OpenSim::ModelComponentSet< ContactGeometry >, OpenSim::ModelComponentSet< Coordinate >, OpenSim::ModelComponentSet< Force >, OpenSim::ModelComponentSet< Joint >, OpenSim::ModelComponentSet< Probe >, OpenSim::ModelComponentSet< Controller >, OpenSim::ModelComponentSet< ModelComponent >, OpenSim::ModelComponentSet< Body >, OpenSim::ModelComponentSet< Constraint >, and OpenSim::ForceSet.

template<class T>

virtual bool OpenSim::Set< T >::insert	(	int	aIndex,
		const T &	aObject
	)

inlinevirtual

Insert an object into the array at a specified index.

A copy is made of the object and added to the Set. The original object is unaffected.

This method is relatively computationally costly since many of the array elements may need to be shifted.

Parameters

aObject	Object to be inserted.
aIndex	Index at which to insert the new object. All current elements from aIndex to the end of the array are shifted one place in the direction of the end of the array. The specified index must be less than or equal to the size of the array. Note that if aIndex is equal to the size of the array, the insertion is equivalent to an append.

Returns: True if the insertion was successful, false otherwise.

template<class T>

Set<T>& OpenSim::Set< T >::operator= ( const Set< T > & aSet )

inline

Assign this set to another set.

This operator makes a complete copy of the specified set; all member variables and objects in the set are copied. Because all objects are copied, this set takes ownership of the newly allocated objects (i.e., _memoryOwner is set to true. So, the result is two independent, identical sets, with the possible exception of the _memoryOwner flag.

Parameters

aSet	Set to be copied.

Returns: Reference to this set.

template<class T>

T& OpenSim::Set< T >::operator[] ( int aIndex ) const

inline

Get a pointer to the set object at a specified index.

This operator is intended for accessing set objects with as little overhead as possible, so no error checking is performed. The caller must make sure the specified index is within the bounds of the array. If error checking is desired, use ArrayPtrs::get().

Parameters

aIndex Index of the desired element (0 <= aIndex < _size).

Returns: Reference to the array element.

Exceptions

Exception if a NULL pointer is encountered.

See Also: get().

template<class T>

virtual bool OpenSim::Set< T >::remove ( int aIndex )

inlinevirtual

Remove an object from the array at a specified index.

If this set is set as the memory owner, the object is deleted when it is removed.

This method is relatively computationally costly since many of the array elements may need to be shifted.

Parameters

aIndex Index of the value to remove. All elements from aIndex to the end of the array are shifted one place toward the beginning of the array. If aIndex is less than 0 or greater than or equal to the current size of the array, no element is removed.

Returns: True if the removal was successful, false otherwise.

Reimplemented in OpenSim::ForceSet.

template<class T>

virtual bool OpenSim::Set< T >::remove ( const T * aObject )

inlinevirtual

Remove an object from the array by specifying its address.

The object is deleted when it is removed.

This method is relatively computationally costly since many of the array elements may need to be shifted.

Parameters

aObject Pointer to the object to be removed. If an object with the specified address is not found, no action is taken.

Returns: True if the removal was successful, false otherwise.

template<class T>

void OpenSim::Set< T >::removeGroup ( const std::string & aGroupName )

inline

inline

Search for the largest value in the array that is less than or equal to a specified value.

If there is more than one element with this largest value, the index of the first of these elements can optionally be found, but this can be up to twice as costly.

This method assumes that the array element values monotonically increase as the array index increases. Note that monotonically increase means never decrease, so it is permissible for adjacent elements to have the same value.

A binary search is performed (i.e., the array is repeatedly subdivided into two bins one of which must contain the specified until the approprite element is identified), so the performance of this method is approximately ln(n), where n is the size of the array.

Parameters

aObject	Value to which the array elements are compared.
aFindFirst	If true, find the first element that satisfies the search. If false, the index of any element that satisfies the search can be returned- which index will be returned depends on the length of the array and is therefore somewhat arbitrary. By default, this flag is false.
aLo	Lowest array index to consider in the search.
aHi	Highest array index to consider in the search.

Returns: Index of the array element that has the largest value that is less than or equal to aValue. If there is more than one such elements with the same value and aFindFirst is set to true, the index of the first of these elements is returned. If an error is encountered (e.g., the array is empty), or the array contains no element that is less than or equal to aValue, -1 is returned.

template<class T>

virtual bool OpenSim::Set< T >::set	(	int	aIndex,
		T *	aObject,
		bool	preserveGroups = `false`
	)

inlinevirtual

Set the object at a specified index.

A copy of the object is NOT made. If getMemoryOwner() is true, this Set takes over ownership of the object and deletes it when the Set itself is deleted.

Parameters

aIndex	Index of the array element to be set. aIndex must be greater than zero and less than or equal to the size of the array. Note that if aIndex is equal to the size of the array, the set is equivalent to an append.
aObject	Object to be set.
preserveGroups	If true, the new object will be added to the groups that the object it replaces belonged to

Returns: True if the set was successful, false otherwise.

template<class T>

virtual bool OpenSim::Set< T >::set	(	int	aIndex,
		const T &	aObject,
		bool	preserveGroups = `false`
	)

inlinevirtual

Set the object at a specified index.

A copy is made of the object and added to the Set. The original object is unaffected.

Parameters

aIndex	Index of the array element to be set. aIndex must be greater than zero and less than or equal to the size of the array. Note that if aIndex is equal to the size of the array, the set is equivalent to an append.
aObject	Object to be set.
preserveGroups	If true, the new object will be added to the groups that the object it replaces belonged to

Returns: True if the set was successful, false otherwise.

template<class T>

void OpenSim::Set< T >::setCapacityIncrement ( int aIncrement )

inline

Set the amount by which the capacity is increased when the capacity of of the array in exceeded.

If the specified increment is negative or this method is called with no argument, the capacity is set to double whenever the capacity is exceeded.

Parameters

aIncrement Desired capacity increment.

template<class T>

void OpenSim::Set< T >::setMemoryOwner ( bool aTrueFalse )

inline

Set whether or not this set owns the memory pointed to by the pointers it holds.

Parameters

aTrueFalse If true, all the memory associated with each of the pointers in this array are deleted upon the array's destruction. If false, deletes are not issued for each of the pointers.

template<class T>

virtual bool OpenSim::Set< T >::setSize ( int aSize )

inlinevirtual

Set the size of the array.

This method can be used only to decrease the size of the array. If the size of an array is decreased, all objects in the array that become invalid as a result of the decrease are deleted.

Note that the size of an array is different than its capacity. The size indicates how many valid elements are stored in an array. The capacity indicates how much the size of the array can be increased without allocated more memory. At all times size <= capacity.

Parameters

aSize Desired size of the array. The size must be greater than or equal to zero and less than or equal to the current size of the array.

Returns: True if the requested size change was carried out, false otherwise.

template<class T>

void OpenSim::Set< T >::setupGroups ( )

inline

Setup groups (match group member names to set members).

template<class T>

void OpenSim::Set< T >::trim ( )

inline

Trim the capacity of this array so that it is one larger than the size of this array.

This is useful for reducing the amount of memory used by this array. This capacity is kept at one larger than the size so that, for example, an array of characters can be treated as a NULL terminated string.
